SubjectRe: [PATCH] mm/sparse: don't check return value of alloc_bootmem calls

It panics iff slab is not available to allocate from yet, otherwise it's
just a wrapper around kmalloc(). This emits a warning to the kernel log,
though, so __alloc_bootmem_node() should certainly not be called that late
in the boot sequence.

Since __alloc_bootmem_node_nopanic() is the way to avoid the panic, I
think the change that should be made here so to panic even when the
kmalloc() fails in __alloc_bootmem_node(), __alloc_bootmem_node_high(),
and __alloc_bootmem_low_node().
